2, according to the air supply way points, there is centrifugal dryer and axial hair dryer. Centrifugal motor drive the blades rotating, made into hair dryer air
centrifugal inertial force, constantly to the outside wind. Its shortcoming is to drain the wind didn't all through the motor, the motor temperature is higher;
Advantage is the noise is low. Axial motor to drive the blades rotating, push into the hair dryer air axial flow, constantly into wind outside. It advantage is to get
rid of all the wind flowing through the motor, the motor cooling conditions, the insulation is not easy to aging; Its disadvantage is that the noise is larger.
3, according to the shell materials, with metal type hair dryer and plastic type hair dryer. Metal type hair dryer durable, can withstand higher temperatures. Hair
dryer light weight plastic type, insulation performance is good, but easy to aging, and high temperature resistant performance is poor.
